During a promotion event for the upcoming film 'Because I Love You', Kim Yoo Jung, Cha Tae Hyun, and other actors stood on stage and greeted the press as well as fans. The controversial issue surrounds Kim Yoo Jung's behavior, more specifically her posture, during this event. 

As you can see below, Kim Yoo Jung is spotted leaning on one leg, playing around with her hands, looking at her nails, and lacking attention toward her surroundings.

Netizens found her stage behavior unpleasant, and criticized with the words, "She's old enough to know better... It's unpleasant to watch her", "Lack of professionalism", "At first, I thought it was no big deal but if she's on stage, she has to show perfection because that's her job", "That's so unmannerly", and more. 

Meanwhile, it was recently revealed that Kim Yoo Jung was sent to the emergency room after the promotion event and canceled an upcoming schedule for recovery. Some netizens are even linking her sudden trip to the ER and schedule cancellation as her label's attempt to subside the issue that is quickly becoming controversial.
